Eltec Gigaohm Resistors 108...1012 Ohms
Eltec Gigaohm Resistors are well known as the lowest noise resistors available, specifically at the low frequencies used in thermal infrared detectors, piezoelectric and pyroelectric sensors and high impedance probes. However, they are not suitable for high voltage or high precision (voltage divider) applications due to the quantum effects of their operation (relatively high voltage- and temperature coefficient)
Eltec Instruments makes low noise resistors from Gigaohms to Teraohms

Typical Applications

  • Low Noise, High Gain Feedback Resistors
  • Low Current Biological &
    Medical Instrumentation
  • Photon Infrared Detectors
  • Piezoelectric Sensors
  • pH Probes
  • High Impedance Load Resistors
  • Charge Amplifiers
  • Ionisation Chambers

Do you have a problem measuring Gigaohms ?

 Eltec resistors are delivred with their exact ohmic value (in small quantities)
All Eltec resistors shipped in small quantity (up to 10 pcs. per value) come with an individual identification tag showing the actual resistor value, such as 5.1 x 109 Ohms.
The accuracy of this value is typically 1%.
It also includes a Quality Report number for traceability.
